Ferrari's Formula 1 turbocharger problems ruined Sebastian Vettel's qualifying and prevented Kimi Raikkonen from starting last weekend's Malaysian Grand Prix.
In this latest video from weekly programme The Flying Lap, Craig Scarborough explains the cause of the turbo problems that had such a big impact on the Sepang weekend.
Ferrari also introduced an upgrade package in Malaysia, which is analysed in a second video with the latest 3D model of the car produced by Motorsport TV.
The first part of the package was the revised bargeboard area.
"The shape's changed with this new extra forward board and then the whole shape of it has been angled backwards," says Scarborough, who goes on to explain the effect of this modification.
There were also changes to the cooling inlets in the rollhoop area that improved cooling for the heat of Malaysia, which has been retained for this weekend's Japanese Grand Prix.
